ForgeIt is a key equipment for metal hot forging processing. By heating the metal blank to an appropriate temperature, it has better plasticity and facilitates forging and forming. In modern industrial production, high-quality mechanical parts and engineering components often require forging processes to obtain excellent mechanical properties and metal structures.
Working characteristics of forging furnace
The forging heating temperature is usually controlled above the recrystallization temperature of the metal and below the austenitization temperature. The specific temperature range varies depending on the metal material. The forging temperature of steel is generally between 800℃ and 1250℃, while the forging temperature of non-ferrous metals such as aluminum and copper is relatively low. The forging furnace needs to provide a stable and uniform heat source to ensure that the blank remains at the appropriate temperature throughout the forging process.
Main types of forging furnaces
According to heating methods and structural characteristics, forging furnaces are mainly divided into the following categories:
Flame Forge: It uses natural gas, coal gas or heavy oil as fuel and is directly heated by flame. The equipment investment is relatively low and the operation is flexible. Suitable for medium and small batch production.
Electrically heated forging furnace: Using the principle of resistance heating or induction heating, the temperature control is precise, the thermal efficiency is high, and there is no combustion exhaust gas emission. It is especially suitable for areas with sufficient power supply.
Regenerative forging furnace: Using advanced heat storage technology to recycle flue gas waste heat to preheat the air, the thermal efficiency can reach more than 60%, and the energy saving effect is significant. It is an environmentally friendly forging furnace currently being promoted.
Forging process requirements for heating furnaces
High-quality forgings require a forging furnace to meet the following process requirements:
1. temperature uniformity: The temperature difference at each point in the furnace should be controlled within ±15°C to avoid uneven structure and performance of forgings due to uneven temperatures.
2. Heating speed: Reasonable heating speed can prevent excessive thermal stress in the blank and reduce crack defects.
3. Insulation ability: Good furnace insulation performance ensures that the temperature of the billet is stable during the insulation stage.
4. Furnace capacity: Select the appropriate furnace type according to the production batch to ensure production efficiency and energy utilization.
Application scope of forging furnace
Forging furnaces are widely used in the forging processing of various metal materials:
- Aerospace: Aircraft landing gear, engine blades, turbine disks and other key components
